Abstract (en)
[origin: EP0923998A2] A wet pipeline through which a hydrate-forming gaseous fluid is to be passed, is first treated by contacting the water therein with a liquid which forms an azeotropic mixture with water. In this way, evaporation of the azeotropic mixture, when the gas is passed through the pipeline, does not result in a water concentration which will form hydrates with the hydrate-forming gaseous fluid.
